Review - Article Example The control phenomenon is attributed to a gating system of cell division within the eukaryotic organisms. Consequently, the purpose of the research was to ascertain whether prokaryotes would also manifest circadian control in the period of cell division timing. In order to achieve this, the authors measured cultures of DNA content, cell division rate, gene expression and cell size. This measurements were carried out on the prokaryotic cyanobacterium Synnechococcus PCC 7942. The results indicated that populations were rapidly dividing at 10h periods of circadian gating of cell division. The experiment proved Synechococuss cells, with extensive circadian rhythms of gene expression and cell division, exhibited double growth rate that were significantly greater than once per 24h. Another new an important finding by the research article showed that Synechococcus cells had the ability to simultaneously sustain double circuits timings that exhibited different timing periods.

Royal national lifeboat institute - Case Study Example The name was subsequently changed to the Royal National Lifeboat Institution in 1854, when cork lifejackets were first issued to crew members. Since its inception, the RNLI has saved more than 139,000 lives , the proof of which are the innumerable stories of courage of sailors and volunteers who have stood the social and technological change over a period of time. The purpose, vision and values of RNLI clearly define their activities i.e. Purpose is â€Å"saving lives at sea†, Vision is to â€Å"end preventable loss at sea† and the Values are â€Å"selfless, dependable, trustworthy and courageous†. Their philosophy is not to seek funding from the government but the lifesaving service is provided by volunteers, and the organization is supported by contributions, donations and legacies on a purely voluntary basis. The entire operation is performed through local teams but with resources and directions from a central location. They have gained expertise through the h istory and tradition of the RNLI’s achievement of almost two centuries. The whole objective is to carry out preservation of life at sea and on the water, primarily by prevention and rescue operations. Introduction This report is a case study of Royal National Lifeboat Institute. ... It was founded by Sir William Henry on 4th March 1824. It was started with the name of National Institute for the Preservation of Life from Ship wrecks; after thirty years it was named Royal National Lifeboat Institute (RNLI). The idea of this Institute came up in his mind when he was on the Isle of Man and had witnessed the treacherous nature of the sea causing dozens of accidents of ships. So he decided to save their lives and then at his appeal, this charity was founded. In 1854, lifejackets were issued to the crew first time. In 1891, the first street collection was held at Manchester. This charity is established with the purpose of saving lives at sea. Its vision is to end preventable loss of life at sea. They all are dedicated towards their vision. They work together like a team to come up with the situation. Till now RNLI has saved more than 139000 lives. Now it has 444 lifeboats and 235 lifeboat stations. For saving lives, it has two main categories of lifeboats:- All weather boats: Weight of large boats is more than 40 metric tons, 1250hp engines, its speed is 25knots and its cost is around ?2 millions. Inshore lifeboats: These are small boats which work at the shores and are able to operate in shallow waters. It has different types of lifeboats for different places. When any incident occurs at the sea, then firstly it gets all the detail about the incident from the coastguard and then the crew can plot a course to the casualty. After arriving at the scene, they tell about their arrival to the coastguard and after that they assess the situation and take up the further steps. If possible they had a talk With the casualty and provide them reassurance.
